Although Mount Baker has not produced another caldera forming eruption since the Kulshan Caldera, the threat of a repeat event of a lesser magnitude remains. This volcano does have an unusually large magma chamber, although its recent eruptions have been quite small. During the 1800s, Mount Baker erupted 17 times and was even more active than Mount Saint Helens during that century (which had 12 eruptions). If by chance you have a photo of the thick white ash beds from the Kulshan Caldera, feel free to email me them at tccatron@asu.edu. You might find a layer of white ash embedded in rock nearby if you live in the area outlined in this video which experienced >6 inches of ashfall.
I have a sample of an unidentified white ash layer from near Mount Baker that a relative gathered while on a road trip. I do not know if it is this same eruption or a different one.
Can you do a video about the McDermitt Caldera in southern Oregon? The caldera apparently has some of the highest concentrations of Lithium in the United States. anyways great videos! plz and thxs you!
As someone who lives where ash would fall should a large eruption occur in the Cascades, you had me panicking when I first saw the title of the video with the word "recent" in it. Then as the video went on I remembered what the term "recent" means to geologists.
@@Leyrann I choose not to worry. I've studied volcanology enough to know that the big ones are extremely rare and unlikely to happen in our lifetime. That being said, that same knowledge means I know what could happen when it eventually does happen, so seeing a fresh post of a "recent" megaeruption got the adrenaline going for a second.
I need like a volcano primer for dummies where you discuss the various terms, rock types and the basic recipe for formation of volcanos. You obviously know your stuff so well but I do not. Would be nice to understand the terms and processes you discuss. Thanks for all your hard work putting these together. This is my new favorite channel!
I remember this being the volcano everyone was worried about when I was a kid, not St Helens. We even joked about it erupting while camping in the national forests around it. Then St. Helens goes and throws a fit overnight and everybody seemed to forget about Baker. I think this is the first video I have seen even calling attention to its potential danger.
@@GeologyHub I seem to recall reports of a few steam venting episodes on Baker in the 70s but like I said I was a kid then so not sure of the dates. I know it was before 75 because we camped up there that year after we got run out of the Olympics by a forest fire and there had already been some of these events.
Considering the potential failed intrusion in the 70's it definitely deserves some attention. I've never really heard any concern about it erupting though, the hype has definitely died a lot in that case. Interesting, considering all the major rivers that flow off of it and the heavy glaciation, not to mention all the surrounding towns. Either way its a lovely mountain, incredibly underrated in all aspects in my opinion.
There is a eruption you should cover about Mt Rainier which leveled over a thousand feet of summit in a Mt St Helen’s type of eruption and caused the massive Lahar known as the Oceola Mudflow which created land where the cities of Tacoma and other parts of the Puget Sound.
When I lived in Tukwila, my apartment advertised by being the tallest apartment in Tukwila - giving an amazing view of Rainier. Over time it really set in - as astoundingly beautiful as it is, my god is that a risky place to live….
Great videos! It would be nice to know some of the chemistry behind these eruptions. Why does the mixing of the two magma types provoke an explosive eruption?
Add water flash to steam pressure from heat builds up hydrogen seperates from oxygen boom you have a hydrogen explosion. Best and simplest way i can explain
Hi! Geo student. In a subduction zone the colliding plate, the Juan de Fuca, scrapes along underneath the NA plate. To create a melt in the lithosphere we can either raise the temperature, lower the pressure, or add volatiles into it, called flux melting. As the melt grows, fed by the subduction and asthenospheric convection, it builds up and we get these hot spots, that feed the volcanoes. The thing is, the type of eruption is dependent on a few things, one of which is composition. Oceanic crust tends to be very dense, very low silica content, which is why it makes very low viscous, very runny lava. Continental crust on the other hand is very high silica, so it is very viscous, and produces high SO2 releases. This plus steam flash leads to bigger explosions
Its funny to hear you pronounce things near me. Living here I never realized that some of those words might be pronounced differently by someone else. Also can you do a feature on the chocolate hills in the Philippines? I went there, it's pretty cool.
@@GeologyHub They're really cool. We climbed to the top of one to see the whole field of them. I'd be interested to know why they're there and how they got there. Thanks!
Fantastic video as usual, youre chanel has quickly become my favorite RUclips. Could you possibly cover the Askja caldera or the móðuharðindi/lakagígar of 1783?
It’s always crazy when you get to the end of describing these massive eruptions that devastate huge areas, and then they get classified as a VEI6 and I realize there are two magnitudes higher…
I grew up near Maple Falls, seeing Mt. Baker every day, and had no idea it had such an intense history! Your videos are amazing, thank you for all the time you put into them!
Thanks for covering these little known volcanoes. The Cascades are well known, but the individual mtns. & calderas, not so much, unless 1 is a local. A km.-deep ashfall is impressive, & stands as a reminder of what these pimples are capable of. Again, thanks for the great info.
I was curious to know how are scientists able to date past eruptions so far back? Are these dates accurate or guesses? Thank you for very informative videos!
The dating of past eruptions relies on a technique called radiometric dating. You find a radioactive element that has been caught in an unchanging millieu (from an eruption, something that has been caught in crystals as the ash/lava/magma cooled down). Radioactive isotopes decays at a fixed rate and we know this rate very very well. As they decay, there will be less of the starting isotope and more of what is called the daughter isotope. So, if you measure the amount of the starting isotope and the daughter isotope and compare it to it's decay rate (often we use it's half life instead), you can get a very good determination of the date the eruption happened. If you wish to know more details I can put them in another post. Else, you can read the Wikipedia article on Uranium-Lead dating and Radiocarbon dating.
Nick Zenter's video on "Supervolcanoes in the Pacific Northwest" (yes, seriously) is also excellent. When you go back about 10-20 million years ago, the volcanic activity here is connected to the movement of the Yellowstone hotspot. Or rather, the North American plate moving over it.
Thanks for the video! Hard to find info on this caldera so I'm glad you covered it. Could you possibly do the Hannegan Caldera at some point? That one seems like it rivals Mazama in erupted volume.
There’s 2 spots on the west coast that could have a eruption like that one day the first spot is right below South Sister volcano in Oregon and the other spot is Clear Lake volcanic field in California.
It's a miracle we haven't had any devastating eruptions in North America for this long. I think that's why so many people are so interested because all our volcanoes have made lots of threats over the years but haven't had a truly massive eruption that devastated massive areas in awhile but we all know what our volcanoes are capable of and it's a bit nerve racking!
There is basically a lull in activity when it comes to volcanoes on the westcoast and in states like Nevada, Utah or Arizona. However sometime this will end and activity will start to pick up again. There is an ongoing EQ swarm under St.helens attributed to movement of fluids, lets see what that is going to lead to.....
The Wa cascades are littered with ghost volcanoes. Meaning volcanoes that have had their time of activity and lost their magma chamber went dormant. Eventually being eroded away. Goat Rocks is a example of this eroding away process. Some day all 5 volcanoes in Wa will slowly follow the path as the Goat Rocks volcano.
You can find volcanic rocks and ash from this near my favorite city in Washington called Stehekin, which has no roads going to it, only a boat ride across the long and narrow lake. If you wanted to hike to this volcano that's probably the nearest place where humans live so that would be your starting point, too. If you had mentioned the closest city like you normally do, that would be it, everyone who has a few days or a week to spare should visit there, it is cool.
When you look at Mt. Baker from Bellingham, Ferndale and Blaine, you can see that there was a second peak. The remains from this second peak could be Colfax peak and Black Buttes
thank you for these productions. I live on lone mnt, big sky montana. lone mnt. is known as a 'Christmas tree' volcanic land form, within the Yellowstone volcanic complex. if this interests you, please consider doing a program on this type of volcanic activity / resulting landform. again, thank you for your productions here.
Like the other volcanoes in the Cascade range, we climbers smell a modest bit of hydrogen sulfide during ascents. Playing Frisbee on Baker's summit is a hoot, too.
I've been to Mount Baker many, many times, yet never knew about this feature or the volcanic field even though I'm well aware of how active Mount Baker itself is. I gotta say it might just be my favorite of the Cascades, not only cause its the closest to home but also due to the quite interesting geology of the place. Oh, and of course it is incredibly beautiful up close and from afar.
I saw your update on Mount St. Helens and had a question. I watched a PBS Terra video about the new glacier in Mount St. Helens. What would happen if there was another eruption??
Thank you for this! I can see Mt. Baker from my home in Bellingham and never knew an Eruption that large took place here. I’ve seen that white ash layer while digging in my yard and though it was from a forest fire. Now not only do I know better, but now I know Mt Baker has an unusually gigantic magma chamber. So thanks…I think…
Hello GH, you mention an eruption height of 44km in the large eruption in antiquity. I wonder, how do geologists come to a conclusion like that? Is there a formula used based on the known deposit field size that can be used to extrapolate this ejection column height? Thanks for another great post. Cheers.
I've hiked around Artist's Point on Mount Baker's NE flank many times, and there are lots of geologic features that are clearly remnants of an extinct crater. I always wondered what formed those ash-grey slopes visible from the Chain Lakes trail... now I know.
Could you do a video about underwater volcanoes? I feel that with the planet being 75%-80% water, and lest 10% of that being explored that there's a hole lot of unique volcano types, undersea calderas, and of course fumerals
I would like an explanation for how it is that there are crustal-spreading volcanoes (eg, in inland BC) only a few hundred miles from these subduction-induced volcanoes. How/why is it that spreading and subduction are going on so close to each other?
They crust is like a skin on a simmering pot of stew. As parts stretch and move, you get little tears and weak spots. The strength of these tears or faults vary between each other and over time. There's also forces pushing underneath in the mantle we're not entirely clear on ^-^
We know that volcanoes are classified as "active" if they have erupted during the prior 7.5-10k years. We usually see a list of about 47-51 volcanoes which are currently active. What qualifies entry into the list of currently active volcanoes? Fumaroles? Uplift? Seismic activity thresholds? This might be something to delve into.
If I understand correctly the term active refers to a system which have erupted geologically recently and so can potentially erupt in the future while the count of 47-51 refers to those which are currently erupting molten rock and or ash
Geology Hub, This might not be a good enough question for a video but why do almost all volcanoes have lenticular clouds sitting over the top of them? Is this just coincidence, is there some sort of geological/scientific effect that keeps the cloud there for eg, like a magnet would attract iron filings. Surely it's not just because of their height as there are many many clouds go over Mount Fuji but still there is a lenticular cloud bang smack over the crater almost all the time. Always perfectly centred over the craters of each volcano, I just find it strange, even kinda spooky lol. Sorry if it's a stupid question but if you don't ask, you'll never know.
>Living right next to Mount Baker lol. It's not scary or anything. Pretty chill volcano. Also has steam vents on the Eastern side so it vents pressure weekly.
Hey I'm really enjoying your videos and I'm curious if all these frequent eruptions are typical? I feel like I've heard so much about eruptions lately and I'm wondering if that's because its happening more frequently than usual or it's my searches and the algorithms.
The current rate of eruptions is normal and close to the average. We're more aware because of all the videos and other info available on the web. Also, this exceptionally informative channel covers a lot of geologically recent (within the past million years) events that would be far more than ancient in another context.
I'd also add that there seem to have been more eruptions near 1st world towns and islands lately, which means they get more press and more tourism and also that the locals can afford to produce their own coverage.
The real danger would be the lahars. As long as you're not near the Nooksack river it would probably just rain a ton of ash with what Mount Baker would likely produce.
Check out Alex Fillipenko in his presentation lectures on astronomy. If you would kindly slow your speed significantly and amplify your enthusiastic love of geology and tectonics, you will have my gratitude! My driving instructor, a million years ago, aptly stated, “If you go slow, you (and I’ll add OTHERS!) won’t have to think fast!” One more observation… If the material you present in rapid fire would be on a class examination, you’d have to grade it on a steep curve since no one would otherwise get a passing grade! I’m sure I’m not alone with my thoughts…thank you!
Well, old or recent is relative. This was about a million years ago. The flood basalts that covered much of eastern Washington and Oregon with lava were about 14-17 million years ago. And even that could be called recent in geologic terms.

Yep, recent is relative to geologists. For some who work in ancient cratons such as Hudson Bay, “recent” means anything younger than 400 million years

It's a beautiful mountain to hike through, with easy access to sulfur crystals.
Can you do the dead volcanoes in the UK. Like Ben Navis and Arthur’s Seat.
If you live in Washington, look up Professor Nick Zentner., At WSU. You'll find all you need to know
Baker is an amazing volcano
I asked for a Kulshan Caldera in the comments a few videos back, and here it is. Bitchin'.
Could you do story on Carter Lake in Oregon
What if you covered the basalt lava flood in Washington state?
Nvm I just found it
Can you do an analysis on Mars largest volcano?
can you do a video on the tawau hills its in malaysia sabah snd i think its a volcano chain
The dates are inflated (maximum 4,500 years).
Hey I'm really enjoying your videos and I'm curious if all these frequent eruptions are typical? I feel like I've heard so much about eruptions lately and I'm wondering if that's because its happening more frequently than usual or it's my searches and the algorithms.
The current rate of eruptions is normal and close to the average. We're more aware because of all the videos and other info available on the web. Also, this exceptionally informative channel covers a lot of geologically recent (within the past million years) events that would be far more than ancient in another context.
I'd also add that there seem to have been more eruptions near 1st world towns and islands lately, which means they get more press and more tourism and also that the locals can afford to produce their own coverage.
What size volcanoes are they in the alps
None
What I've never heard of this
Would have been nice to know what the number 1 was in teh last 2 million years but otherwise good as usual, thanks! :)

Oh dear.. i live in bellingham.. 30 miles west of baker..
The real danger would be the lahars. As long as you're not near the Nooksack river it would probably just rain a ton of ash with what Mount Baker would likely produce.
I don’t have no idea what’s going on down the line honestly
:28 got your Wenatchee wrong (is we-natch-ee)
As a Washington resident....I kept cringing at how you were pronouncing areas in the state.
Won't be so hot this summer
Bonjour, Nevado d'El Ruis en Colombie.
What about the new Mexico caldera grande
If this eruption happened where I lived we would be safe from rising seas

Day 2 of asking geology hub to make a video of musan

Check out Alex Fillipenko in his presentation lectures on astronomy. If you would kindly slow your speed significantly and amplify your enthusiastic love of geology and tectonics, you will have my gratitude! My driving instructor, a million years ago, aptly stated, “If you go slow, you (and I’ll add OTHERS!) won’t have to think fast!” One more observation… If the material you present in rapid fire would be on a class examination, you’d have to grade it on a steep curve since no one would otherwise get a passing grade! I’m sure I’m not alone with my thoughts…thank you!
I know where a gold mine is that the guys are separating gold from white pumice material.. i bet there is plenty more...
Apparently “recent” is subjective. 🙄
👍
1.15 million years = recent
*This is not about ANY recent eruption, this is just about some super old eruption.*
Well, old or recent is relative. This was about a million years ago. The flood basalts that covered much of eastern Washington and Oregon with lava were about 14-17 million years ago. And even that could be called recent in geologic terms.
